Step-by-step explanation:
We have been given the linear regression equation for a data set is y=-2.8x+70.8 where y is the temperature in degrees Fahrenheit and x is the number of hours since 8 am.
We can see that our given line is in slope-intercept form: , where, m = Slope of line and b = y-intercept.
Upon comparing our given equation with slope intercept form we can see that the slope of the equation (m) is -2.8. The slope represents that temperature is dropping at a rate of 2.8 Fahrenheit per hour after 8 am.
Answer:
3
Step-by-step explanation:
2 1/4 = 9/4
9/4 divided by 3/4 = 3
Step-by-step explanation:
Graph it and find the rise over run. which then gives you your slope
Answer:
An inherent zero is a zero that implies none
Step-by-step explanation:
A zero which means that a phenomenon or variable does not exist or isn't represented is called inherent zero. It simply implies none.
Datasets that have inherent Zero:
1. Average age of participants In years
2.) Rainfall height in inches during rainy period
3.) Speed of wind during a storm.
Datasets with no inherent zero :
Dataset which involves measuring constructs usually have no inherent zero, such as :
1.) Average IQ level in a group of students
2.) Average level of satisfaction
3.) measurement involving temperature
Answer:
The answer to your question is letter B or C they have the same response.
Step-by-step explanation:
From the graph we get the center and the radius
- The center is the point shown in the graph and its coordinates are (1, -4).
- The length of the radius is 3 units, from the center we count horizontally the number of squares (3)
Substitution
(x - 1)² + (y + 4)² = 3²
or (x - 1)² + (y + 4)² = 9
